Bambu Lab A1 Auto-Calibrating, Multi-Color, 256 mm Bed Slinger
A full-size 256 mm bed slinger that auto-calibrates itself, prints to 500 mm/s, runs whisper-quiet, and adds 4-color printing with the AMS lite — from $399.
The Bambu Lab A1 brings Bambu’s automation to an affordable, full-size bed slinger: it auto-levels the bed, calibrates flow, and compensates for vibration on its own — no manual tuning — then prints at up to 500 mm/s on a 256 mm bed. A quick-swap all-metal 300°C hotend, a textured PEI plate, and Active Motor Noise Cancellation make it quiet and easy to live with, and the optional AMS lite adds automatic 4-color printing.

The easy-to-own Bambu, at full size.
The A1 takes the parts of Bambu Lab that people love — automatic calibration, genuinely fast printing, and clean multi-color — and puts them in an affordable, full-size 256 mm bed slinger. It levels the bed, dials in flow, and tunes out vibration on its own, so a first print succeeds without the leveling rituals open-frame printers usually demand. A quick-swap all-metal hotend, a textured PEI plate that releases parts cleanly, and Active Motor Noise Cancellation make it quiet and friendly enough for a desk, a classroom or a small farm. Add the AMS lite and it prints in four colors automatically. Here is what makes it worth owning.
Automatic bed leveling, flow-rate calibration and vibration compensation run themselves — no manual leveling, no babysitting the first layer.
Up to 500 mm/s and 10,000 mm/s², kept clean by input shaping and pressure advance so speed doesn’t cost surface quality.
Add the AMS lite for automatic four-color printing, with RFID recognition of genuine Bambu Lab filament that loads settings for you.
Active Motor Noise Cancellation keeps the A1 quiet enough for a bedroom, office or classroom — it disappears into the background.
An all-metal 300°C hotend with a tool-free quick-swap nozzle handles PLA, PETG, TPU and PVA and makes nozzle changes a one-minute job.

Fast prints, kept cool and clean
The A1 runs up to 500 mm/s with 10,000 mm/s² acceleration, and active part cooling plus input shaping keep those speeds from costing quality — sharp corners, clean overhangs, and no ringing on a bed slinger that would normally blur at pace.

Start it, and watch it, from your phone
The Bambu Handy app sends a print from your phone, tracks progress with live status, and stores your models in the cloud — kick off a job from the couch and check on it from anywhere, without walking back to the machine.

It sets itself up. You just print.
The calibration steps that wreck most prints, automated.
The A1 levels the bed automatically, runs a flow-rate calibration for the loaded filament, and measures and cancels its own vibration — the three things that decide whether a print succeeds — without a single manual adjustment.
On a typical open-frame printer, a good print starts with a chore: tram the bed, set the Z offset, tune the e-steps, fight ringing. The A1 does all of it for you. A sensor in the toolhead maps the bed and sets nozzle height for a clean first layer; a dynamic flow-calibration pass dials extrusion to the exact filament so walls aren’t over- or under-fed; and accelerometers measure the machine’s own resonance so input shaping can cancel the vibration that causes ghosting at speed. For a first-time owner that means a part comes out right on day one; for a classroom or a small farm it means every unit and every new operator gets consistent results without years of tuning intuition. You load filament, pick a model, and press print.
Full-auto calibration — every step, hands-free
Four colors, fully automatic.
Add the AMS lite and print in color.
The A1 is AMS lite ready. The AMS lite holds four spools and switches between them automatically mid-print, with RFID recognition that loads each genuine Bambu Lab filament’s settings for you — four-color models and multi-material prints, hands-off.
Multi-color used to mean manual filament swaps and guesswork. The AMS lite makes it automatic: it feeds and changes between four spools without intervention, reads filament type and color from RFID so the right profile loads itself, and works directly in Bambu Studio so coloring a model is a click, not a project. That opens up full-color figures, multi-part assemblies printed in one job, and color-coded functional parts — the kind of work that makes a printer fun to own and genuinely useful in a classroom. The AMS lite is optional and modular, so you can buy the A1 now and add color later. Rev1 can bundle the AMS lite and a starter set of filament so you are printing in color out of the box.
Fast, quiet, and easy to live with.
Speed you can use, on hardware that lasts.
The A1 runs to 500 mm/s with 10,000 mm/s² acceleration, kept clean by motion compensation, while a 100°C textured PEI plate releases parts on its own and Active Motor Noise Cancellation keeps it quiet.
Fast printing only matters if the parts come out right and the machine is pleasant to be around. The A1’s motion system pairs high speed with input shaping and pressure advance so corners stay sharp and walls stay smooth at pace, turning an overnight print into an afternoon one. The all-metal 300°C hotend takes a tool-free quick-swap nozzle, so changing from a fine 0.2 mm to a fast 0.8 mm is a one-minute job, and the flexible textured PEI build plate pops parts off without scrapers or glue. Active Motor Noise Cancellation tunes out stepper whine so the machine runs quietly enough for a bedroom, office or classroom. It is a printer you can put on a desk and forget about — in the best way.
Swift maintenance — quick-swap nozzles
Clean surfaces, straight off the plate.
From everyday prototypes to display-quality models.
Because calibration is automatic and the motion system is tuned, the A1 turns out clean, consistent prints without fiddling — smooth spiral vases, crisp functional parts, detailed minis and, with the AMS lite, full-color models. The textured PEI plate leaves a pleasant matte finish on the first layer, and accurate flow keeps walls even and dimensions on target. Whether you are a maker iterating designs, a teacher running a classroom, or a small business printing parts and products, the A1 delivers repeatable results that look like they came off a far more expensive machine. Rev1 can help you pick nozzle sizes, plates and materials for the parts you make most.
From first layer to finished print
Real A1 prints — functional parts, mechanisms, full-color models and fine detail, straight off the textured PEI plate.






Printer or full color combo — your call.
Start single-color, add color when you want it.
Buy the A1 on its own for fast, automatic single-color printing, or choose the Combo to add the AMS lite and print in four colors from day one. Either way it is the same auto-calibrating, quiet, full-size printer underneath — the AMS lite simply bolts on.
The A1 is designed to grow with you. On its own it is a complete, capable printer — auto-calibration, 500 mm/s speed, quick-swap hotend and a color touchscreen — ideal if you mostly print one material at a time. The Combo adds the AMS lite for automatic four-color work, and because it is modular you can always add the AMS lite later if you start with the printer alone. Rev1 helps you decide which makes sense for how you print, bundles genuine Bambu Lab filament to get you started, and supports the setup so your first color print goes right. Genuine hardware, US stock, and a real person on the phone.
Add the AI camera — remote eyes on every print
The optional A1 Camera adds a live view and AI failure detection — watch a print from Bambu Handy anywhere, and get flagged the moment something goes wrong on a long unattended job.
The everyday filaments, dialed in for you.
The A1 is an open-frame printer built for the materials most people print most of the time — PLA, PETG, TPU and PVA — with flow calibrated automatically for each one. It is an open system, so you can run genuine Bambu Lab filament with automatic RFID settings or any standard 1.75 mm spool. For enclosed-chamber materials like ABS, ASA and carbon-fiber composites, Rev1 will point you to the enclosed P1S or X1-Carbon instead.
The workhorses for prototypes, functional parts and display models — fast, reliable, and auto-calibrated for clean results.
The direct-drive extruder handles flexible TPU for gaskets, grips and phone cases without the jams a Bowden setup invites.
With the AMS lite, combine colors and use supports for complex geometry — four-spool, fully automatic switching.
One printer, the everyday material range
From rigid PLA and tougher PETG to flexible TPU and dissolvable PVA supports, the A1 auto-tunes flow for each spool — and with the AMS lite it mixes up to four colors or materials in one model. Genuine Bambu Lab filament loads its own settings by RFID; any standard 1.75 mm spool works too.

Comparison sourced from published manufacturer data at build time; prices are approximate and vary with promotions, tariffs and bundles. The A1’s distinction is full-auto calibration and easy four-color printing with the AMS lite in a quiet, full-size machine at an accessible price. The Creality K1 is enclosed and a touch faster; the Prusa MK4S is a refined open-frame workhorse with a strong upgrade path. If you need an enclosed chamber for ABS or carbon fiber, step up to the Bambu P1S or X1-Carbon — Rev1 will help you match the machine to the parts you make.

Bambu Lab A1 questions.
Does the A1 really set itself up?
Yes. The A1 automatically levels the bed, calibrates flow rate for the loaded filament, and measures and compensates for its own vibration — the steps that cause most print failures — with no manual leveling or Z-offset fiddling. You load filament, choose a model, and print. It is one of the easiest printers to own for exactly this reason.
What is the difference between the A1 and the A1 Combo?
The A1 is the printer on its own — auto-calibration, 500 mm/s speed, quick-swap hotend and a color touchscreen — for single-color printing. The A1 Combo adds the AMS lite, which holds four spools and switches between them automatically for four-color printing. Because the AMS lite is modular, you can buy the A1 now and add it later. Rev1 can compare current pricing and tell you which makes sense.
How many colors can it print, and how?
With the AMS lite, up to four colors. The AMS lite feeds and switches between four spools automatically mid-print, and reads genuine Bambu Lab filament by RFID so the right settings load themselves. You design or download a multi-color model, slice it in Bambu Studio, and the A1 handles the changes — no manual swaps.
What materials can the A1 print?
The everyday filaments: PLA, PETG, TPU and PVA, with flow calibrated automatically for each. It is an open system, so you can run genuine Bambu Lab filament with automatic RFID settings or any standard 1.75 mm spool. The A1 is open-frame, so it is not intended for enclosed-chamber materials like ABS, ASA or carbon-fiber composites — for those, look at the enclosed Bambu P1S or X1-Carbon, which Rev1 also supplies.
Is it loud? Can it run in a bedroom or classroom?
It is quiet. Active Motor Noise Cancellation tunes out stepper-motor whine, so the A1 is comfortable to run on a desk, in a bedroom, an office or a classroom. Combined with the built-in camera and remote monitoring in the Bambu Handy app, you can start a print and walk away.
How fast is the A1, and is fast print quality good?
The A1 prints at up to 500 mm/s with 10,000 mm/s² acceleration. Input shaping and pressure advance keep corners sharp and walls smooth at speed, so you get clean parts in a fraction of the time an older printer would take. For very fine detail you can slow down or switch to a smaller nozzle; the quick-swap design makes that a one-minute change.
Does it come assembled, and does it need the internet?
It arrives almost fully assembled — a few minutes of setup — and auto-calibrates on first run. You can print over the cloud and the Bambu Handy app for convenience, or use LAN-only mode and a microSD card to keep everything local. The choice is yours.
Should I get the A1, or step up to a P1P or X1-Carbon?
Choose the A1 if you want the easiest, most affordable way into fast, auto-calibrating, optionally multi-color printing with the everyday materials. Step up to the enclosed P1S or X1-Carbon if you need to print ABS, ASA or carbon-fiber composites, or want a sealed CoreXY machine with a larger feature set. Rev1 walks you through the trade-offs so you buy the right one once.
How does Rev1 support the purchase?
